Creating lines in sketchup

  1. 1. Creating lines in Sketchup
  2. 2. Lines are a fundamental tool in Google Sketchup software. Lines can be drawn freehand or imported from other sources. In this exercise, we will look at drawing lines using the line tool. Lines are the building blocks in Sketchup that allow us to create surfaces and ultimately 3D shapes.
  3. 3. There are some basic tips we need to keep in mind when drawing lines in Sketchup:
  4. 4. <ul><li>Lines that are intended for surfaces should be co-planer; i.e. flat to each other in a given drawing plane. </li></ul><ul><li>Lines should never cross. If you need to draw lines that appear to cross, stop the lines where they cross and start again on the other side. </li></ul><ul><li>Lines can be drawn to specific lengths by typing in a distance value while drawing a line. </li></ul><ul><li>Lines can use other lines or objects as “inferences” to align endpoints or midpoints. Inferences are created by holding your cursor over a desired object for at least 3 seconds. </li></ul><ul><li>A set of lines must be closed, or continuous AND co-planer in order to create a surface. </li></ul>
  5. 5. Creating a straight line
  6. 6. <ul><li>Start the Sketchup software on your computer. When prompted, choose the “ Simple Template – Feet and Inches” as your template. </li></ul>
  7. 7. <ul><li>Start by selecting the Line tool from the main toolbar at the top of the screen (it looks like a pencil). </li></ul>
  8. 8. <ul><li>Click in the 3D world near the woman’s feet and move your cursor to the right…. Try to get the dotted red line to show indicating that you wish to draw on the “red axis”. This will draw a line on the Ground plane (X-Y) and in the positive X direction. DO NOT CLICK to complete the line! </li></ul>
  9. 9. <ul><li>Find the “Measurements” box in the lower-right corner of the screen. TYPE “10’” (Ten and the foot or apostrophe mark, without the quotes) and hit the ENTER key. Your line will be 10 feet long in the X direction. </li></ul>
  10. 10. <ul><li>Choose the Arrow tool on the main toolbar to end the line creation process. </li></ul><ul><li>If you made a mistake, click on the line to select it and hit the DELETE key on your keyboard. </li></ul>
  11. 11. Creating a second line, perpendicular to the first line
  12. 12. <ul><li>Start by selecting the Line tool from the main toolbar at the top of the screen. </li></ul><ul><li>Place your cursor over the first point of your last line. A Green Dot should appear indicating you are over the Endpoint of the existing line. </li></ul>
  13. 13. <ul><li>Click on that Green Dot and drag up ant to the right “On the Green Axis” where a light green line is drawn under your cursor indicating you are parallel to the green axis. </li></ul><ul><li>TYPE 36 and hit ENTER on your keyboard. Note that Sketchup interprets the number 36 as the distance 36 inches. </li></ul><ul><li>Hit ESC (escape key) on your Keyboard or click on the Arrow tool to end the drawing process. </li></ul>
  14. 14. Using Inferences
  15. 15. An inference reads or picks up a point from another object during the creation process to align objects or features with each other.
  16. 16. <ul><li>We will start from the end of the last 36 inch line you just finished drawing. Start by selecting the Line tool from the main toolbar at the top of the screen. </li></ul><ul><li>Place your cursor over the last point you had drawn on your 36 inch long line and wait for the Green Dot to appear. Click on the Green Dot and move your cursor to the right and down so that it is over the end of the ten foot line. A Green Dot should appear when you are in the correct location. </li></ul>
  17. 17. <ul><li>HOLD your cursor over the Green Dot for three seconds and then move your cursor up and to the right so the green dotted line comes out from your cursor. When you position your cursor approximately 36 inches away, the line you are drawing will turn red and “snap” to the correct inferenced location. </li></ul><ul><li>Click to set the third line at 10 feet long and parallel to the first line. </li></ul>
  18. 18. You have just created an open line made up of three line segments. The three line segments do not make a shape because they are open leaving a gap. Remember, an inference reads or picks up a point from another object during the creation process to align objects or features with each other. Inferences can help you keep lines the same length.
  19. 19. Closing the Line
  20. 20. Let’s finish the line segments by closing the open end to create a closed shape. I’m not going to tell you how to do it, but I have a question for you… If you create a closed shape, what happens to the area inside the shape?
